攻撃内容

攻撃の内容は特定のURLが存在するかを確認する手法で、こいつが本当に面倒なこと。

• 大量にアクセスを送る
• 海外且つ踏み台のサーバーを使用
• IPを変更する
• ブラウザの種類（UserAgent）を変更する

ごく短い間に大量のアクセスを送ってきて、海外のサーバーを使用してIPを変更してブラウザの種類まで変えてくる凶悪なやつです。

対応策

対応策としては大量のアクセスを弾くしかありません。

なのでApacheにモジュールを追加やAWSはWAFを入れて簡単に対応出来ますが今回は説明しません。

サーバー側に対策を入れましたが「一定時間に大量のアクセスをした場合に弾く」処理なので閾値になるまでは弾いてくれません。

僕は不正アクセスするようなやつに出来るだけサーバーのリソースを割きたくない！

なので「攻撃対象のURLは全て403を返す」ようにしました。

.htaccessで特定のURLを含むを弾く

.htaccessを使用して特定のURLに接続しようとするリクエストを弾くことが出来ます

以下を記入することで弾くことが出来ます。

1 2 3 4 5 6 7

<IfModule mod_rewrite.c?>  RewriteEngine on    RewriteCond %{REQUEST_URI} ^.*hoge.php [OR,NC]  RewriteCond %{REQUEST_URI} ^.*piyo.php [NC]  RewriteRule ^(.*)$ – [F,L] </IfModule?>

hoge.php OR piyo.phpを含む場合に403画面を表示します。

最終行は[OR,NC]にすると次行があると判定してしまうためエラーが発生するので注意してください。

フラグには[NC]もしくは[OR]を指定できます。フラグを二つ設定するにはカンマで区切ります。(例: [NC, OR]

• [NC] - 大文字小文字を区別せずにパターンと一致するかどうかをテストします。
• [OR] - いずれかのRewriteCondにあてはまる場合にRewriteRuleを適用します。[OR]を明示しない場合、自動でANDになります。

簡単に導入するサンプル（PHP）

攻撃されたURLを元にサンプルを作成したので活用してください。

※使用しているURLがあるか確認してください。ある場合は該当の行を削除してください。

まとめ

DDosのブルートフォースアタックは性質が悪く対応も完全には出来ません。

今回のURLのアタック対象を見るとわかりますが、Webサービスが完全にPHPとばれてしまっています。

これは色々試してみましたが「http://domain.co.jp/index.php」でトップのページが表示された場合、PHPを使用していることがわかってしまうためかと思われます。

出来れば完全に駆逐出来る方法があると助かるですが、DDosの攻撃は難しいです・・・
